DeltaConvergenceError
¶ The fixed point computation of \(\delta\) failed to converge.
This problem can sometimes be mitigated by increasing the maximum number of fixed point iterations, increasing the fixed point tolerance, choosing more reasonable initial parameter values, setting more conservative parameter or share bounds, or using different iteration or optimization configurations.
